America, and a resident of Corning, New

.York, have invented certain new and useful Improvements in Molds forGlass-Blowing which the following is a speci- Machines, of fication.

My invention has for its object to provide sucha construction ofactuating mechanism for blowing molds as will insure accuracy andsmoothness of their action, a minimum of power required to operate itand simplicity of construction, theoperations which.

are performed in the embodiments here shown, being a closing and openingof the molds, a dropping of the mold a permit the cooling of the moldbyaf-waterbath and a restoration of the molds to normal position. For thispurposeit consists essentially of a horizontally journaled frame havinga cross-head upon which the mold parts are pivoted, the frame carryingcertain parts "of-'- the'mold-actuating mechanisms, which parts aregoverned by other'moldactuatmg parts carried on a fixed part of themachine, the. connection between the two series of actue ating partsbeing such that the frame and parts mounted thereon may readlly beremoved from and replaced in any appropri that shown. in my otherapplication, Serial Number 602,532, filed Jan. 13,1911,- of whichthis-is a division. I

-It further'consistsin the construction, ar-

rangement and combination of the several parts of which it is composedas will be hereinafter more'fully described and claimed. I

Referring to the accompanying drawings in which corresp'ondingparts aredesignated by corresponding-marks of referen'ce: Fig: urel' .is a sideelevationofl one plex machine embodying [my invention. Fig. 2 is a iewpartly in front elevationand partly in section on line zv w of Fig. 1.

' Fig. 3 is an enlarged plan view of the mold,

its actuating mechanism and-its support The main actuating wheel or disk12 mountedin the-frame forms a part of the" blowing ma chine fullydescribed in my aforesaid prlor application 'and it therefore needs nofurther descriptionhere.

'In the bearing 20 projectingfrom one side of the maimframe 1 in thebottom'at the sideofa .du-.

' front end thereof-is joiirnaled tubular I Patented Qct lzflfllfi;Original application filed January 13, 191 1,Se ria1 ism-602,532. Divided and this application'fildsepteniher the depending armzof a bell crank21Ejournaled' at'21 to the side of the .main frame, the upper endof thebellcrank engaging in acam track 21 (shown'iin dotted lines in Fig-. onthe.inner. .face,. of the 'disk- 12.

The outer end of the tubular shaft 20 terminatesin a. cross head, 20 onthe forward end of which is p1voted,.by ,a-pivot pin 20 parallel withthe axis of themoldcavity, the

two halves22, 28, of the separable mold. The cam track 21..is of suchshape that, it

.Will impart a propenmotion to the xibell crank 21 to oscillate thetubular slfifaftthrough alimited arcsufficient to lower the mold halvesinto the coolingv tank? and then raise them. Within thetubular shaft 20'is mounted, for axial and rotary movementy'a 'shaft 24, which extendsoutwardly beyond the cross. l iead.,20land has mounted thereon .collars22fand 23, the collar22 b'eing fast upon the shaft 24, and theeollar' 23'adapted toslide-thereon. The'Ycollai' 22 has two I diametrically 1opposite trunnions 22"' the lower of which is journaled in 1a"; rearwardextensibn 22P'of thesame half 22, while the other. recei-ves theforwardly extending arm of a bell-crank 24 'journaled at' 24* in therear end of the cross'head 20, the opposite arm 'of the bell crank beingconnected by the link24- with. the opposite half 23 of the mold, theconstruction being such that as the collar 22Rislpressed inwardly themold halves are closed, and that as itis moved out-L Wardly they areopened.

To-accomplish the inward movement of the collar 22 is.the*function ofthe collar .23, which is loose'on the shaft 24,11 spring 25 beinginterposed between itand the collar 22 to cushion the closing movementand to provide a certain resiliency. The collar 23 has trunnions thereonwhich are mounted inthe bifurcated end of the forwardly extending armsof a bell crank 26 pivoted at. .26 -to a bracket 26 pro ectmg from theside of the main frame 1. the laterall extending arm of the bell crankbeing connected by a universal joint 27 with the dependmp arm of asecond bell crank 28, pivoted at 28 on the side of the main frame,-theupper arm of the last named bell crank having thereon a roller 28 heldon. a periphery ofthedisk 12- close the mold halves.

the pring 28 will actuate the bell crank 28 thus moving the bell crank26 to again move the collar 23 outwardly. In this movement the collarwillby' contacting with the nut 23 ontheend of the shaft 24, cause anoutward axial movement of the shaft, -'which was pressed inwardly uponthe closing of the mold, restoring the mold parts to open nor malposition. h h

' As shown 1n Fig. 2, I prefer to make the machme a duplexone, that isto sa} to pro 'vide separate mold mechanisms on each side of'the mainframe, as is fully described in my prior application. v c

Having thus described my invention what I claim is.:-

1. In a mold opening and closing and low; ering mechanism thecombination with a shaft, of. mold parts pivoted thereon 'for openingandclosing'movement, means for imparting angular inov'ement to the saidshaft to raise andlower the molds, a second shaft'conc'entric to thefirst named shaftand capable of axial movementin respect there to,connections between the last named shaft and the mold parts to open andclose the same 1,1 sees? and means comprising alever pivot-ed inde-"pende'ntly. of the first named shaft and parts carried thereon forimparting axial move- I ment to the last named shaft.

2. In a mold opening and closing a d lowering mechanism the combinationwith a tubular shaft, mold parts mounted thereon for opening andclosing" movements, a second shaft slidably mounted within the tubularshaft, connections between the last named shaft and the mold parts foropening and closing the same, means for imparting angular movement tothe tubular shaft and means comprising a lever pivoted independentlofthe' tubular shaft and parts carried thereon for imparting axialmovement to the last named shaft.

In, a mold-actuating mechanism, the combinationwith a tubular shaft, ofmold parts mounted thereon for opening and closing movement, a secondshaft slidably mounted within the tubular shaft, two collars upon thesliding shaft, one of which is rotatable thereon connections between oneof the said collars and the mold parts to open and close the sameyalever pivoted in- "dependently of the tubular shaft and connected withthe other collar for reciprocating the sliding shaft and the othercollar, a

spring mterposed between the collars, and means for rotating the tubularshaft,
